What the study found
Adjusting the light color temperature to medium-warm white during the non-stress test was associated with lower stress and anxiety and higher psychological well-being in high-risk pregnant women.
Why the authors say this matters
The authors suggest that light color temperature during the non-stress test may help address the stress and anxiety that high-risk pregnant women can experience during repeated fetal health assessment.
What the researchers tested
This randomized controlled study included 100 high-risk pregnant women. The intervention group underwent the non-stress test after the light color temperature was adjusted to medium-warm white, and outcomes were measured with the Perceived Stress Scale, the Psychological Well-Being Scale, and the State-Trait Anxiety Inventory.
What worked and what didn't
In the intervention group, Perceived Stress Scale scores decreased, Psychological Well-Being Scale scores increased, and State-Trait Anxiety Inventory scores decreased from pre-test to post-test, all with p < 0.05. In the control group, anxiety and psychological well-being showed statistically significant pre-post differences, but perceived stress did not; the abstract says these changes were minimal or unfavorable in magnitude.
What to keep in mind
The abstract does not describe detailed limitations beyond the study setting and sample of high-risk pregnant women undergoing a non-stress test. The report also provides pre-post score changes rather than longer-term outcomes.
Key points
- Medium-warm white light during the non-stress test was linked to lower stress and anxiety in the intervention group.
- Psychological well-being increased in the intervention group after the light adjustment.
- The control group did not show a significant change in perceived stress.
- The study included 100 high-risk pregnant women in a randomized controlled design.
- The authors suggest light color temperature may help during fetal health assessment.
